Today Apple has unveiled the iPhone 5S and it’s flagship feature, the new Touch ID – an integrated fingerprint sensor located under a new sapphire home button that will scan your ‘sub-epidermal layers’ at 500ppi
It appears Apple has designed Touch ID to be faster than entering a four-digit passcode, stating in its marketing materials that using Touch ID is “faster, easier, and even a little futuristic”. It will allow users to store up to five fingerprints, allowing other trusted users access to a locked phone.
Put your finger on the Home button, and just like that your iPhone unlocks. It’s a convenient and highly secure way to access your phone. Your fingerprint can also approve purchases from iTunes Store, the App Store, and the iBooks Store, so you don’t have to enter your password. And Touch ID is capable of 360-degree readability. Which means no matter what its orientation — portrait, landscape, or anything in between — your iPhone reads your fingerprint and knows who you are.
Financial Times reporter Tim Bradshaw shared this video showing how the iPhone learns a fingerprint by scanning a finger a half-dozen times.
